In the ten-episode season four, when an attorney is murdered on the eve of his civil rights trial against the LAPD, Bosch is assigned to lead a task force to solve the crime before the city erupts in a riot.

Bosch must pursue every lead, even if it turns the spotlight back on his own department. One murder intertwines with another, and Bosch must reconcile his past to find a justice that has long eluded him.

“As Amazon Prime Video’s longest-running one-hour series, Bosch has long been a cornerstone of our scripted programming, and Prime members consistently clamor for more,” said Sharon Tal Yguado, Head of Scripted Series, Amazon Studios. “We are excited to give them another season with Harry Bosch, Jerry Edgar, Grace Billets and the rest of the diverse characters that make up the Bosch universe.”
